SPECIFICATION forming part of Letters Patent hi0. 290,833, dated December 25, 1883.

I Application filed Octpber 10, 1883. (No model.)

T 0 all whom, it may concern:

Be it known that I, JAMEs H. ARMSTRONG, 0f Pinconning, Bay county, Wichigan, have invented a new and Improved Chain-Fastener, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved device for drawing chains taut and holding them so.

The invention consists in a forked lever, to which a grablink is pivoted, to which lever a bar is pivoted, to which in turn a latch is pivoted, which latch can be swung against the side of the lever,and held in place in this position for the purpose of holding a chain to draw it taut.

Referenceis to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal elevation of my improved chain-fastener. Fig. 2 is alike view, showing a chain drawn taut. Fig. 3 is a plan view of the same; and Fig. 4 is a cross-sectional elevation of the same on the line as m, Fig. l.

A lever, A, is provided with a chain grab or fork, A, at one end, and at or near the said end of the lever a grablink, B, is pivoted to the same, which link is provided with an aperture, b, from which a longitudinal slot, 1), extends to near the end of the link. A bar, 0, is pivoted to one side of the lever, and is provided at its bottom with a rectangularly-pre jecting forked arm, D, to which a latch-lever, E, is pivoted, which is provided with an angular arm, F, passing between the jaws of the forked arm D. A spring-pin, G, is held by a chain, H, to the bar 0, and is adapted to be.

passed throughan aperture, J, in the latchlever E. One end of the chain K is passed through the grab-link B, and the other end is 1. The combination, with the forked lever.

A, of the grab link B, pivoted to the same, the bar 0, and the latch-lever E, substantially as herein shown and described.

2. The combination, with the forked lever A, of the grab-link B, pivoted to the same, the bar 0, pivoted to the lever A, the latch E, pivoted to the bar 0, the spring-pin G, and the chain H, substantially as herein shown and described.

3. The combination, with the forked lever A, of the grab-link B, pivoted to the same, the bar 0, the latch E, pivoted to the same, and means for holding the free end of the latch E against the lever A, substantially as herein shown and described.
